Web 2.0. I first saw this term back in 2004, when blogs were just starting to become popular in China, and many magazines and newspapers devoted large sections to reporting on their use. Now, it's already 2008. In these five years, the forms of Web 2.0 have been constantly innovating, from blogs to microblogs and then to SNS (Social Networking Services). However, for domestic Web 2.0 services in China, they follow the "C2C" rule, which means "Copy to China." There are hardly any Web 2.0 services with "independently owned intellectual property rights." Despite this, I still feel honored to have personally experienced a transformation of the Web.
